Pitfall 1: B-chav kawm yog cov duab plaub, tsis yog puag ncig - qhov chaw kaw lus hais tus tsav tsheb daim ntawv
Ntau tus kws tsim qauv tsim cov khoom siv coj los siv rau thawj zaug ua rau tus neeg hais lus hloov pauv - vim tias feem ntau "hais lus" hauv lawv lub siab yog puag ncig. Tab sis qhov chaw tshwj tseg rau tus tsav tsheb hauv lub smartwatch, lub nplhaib ntse, lossis ntse band yog ib txoj hlua nqaim ntev. B-chav kawm tsav tsheb yog tsim raws nraim rau qhov chaw zoo li no. Lub Φ15 × 8mm hneev taw txhais tau hais tias 15mm kev taw qhia ua ke nrog lub dab teg txuas ntxiv, 8mm kev taw qhia yog txwv los ntawm rooj plaub dav, thiab 3.0mm thickness zaum ntawm lub mainboard thiab rooj plaub.
Feem ntau yuam kev thaum xaiv tus tsav tsheb los ntawm kev sib tsoo: lub rooj qhib tsis sib haum nrog tus tsav tsheb loj, lub gasket tsis tuaj yeem nias nruj thiab IP68 tsis ua haujlwm; los yog tus neeg tsav tsheb txoj kab uas hla tshaj qhov dav dav thiab tsis tuaj yeem ntsia tau txhua. B-chav kawm duab plaub tus tsav tsheb "ntev ntug" ua raws li cov cuab yeej qhov ntev kev taw qhia, zaum ntws tawm ntawm lub mainboard thaum lub sij hawm mounting, thiab muaj ib qho qhib kev taw qhia - nws yog qhov kev lag luam zoo tshaj plaws rau cov khoom siv.
Pitfall 2: 0.5W rated + kaw rov qab kab noj hniav - nrov tsis zoo
Lub smartwatch rov qab kab noj hniav tsuas yog 0.2 ~ 0.5 cubic centimeters - ib qho me me kaw kab noj hniav . 0.5W ntsuas lub zog suab me me, tab sis thawb lub zog siab dua hauv cov kab noj hniav no ua rau muaj teeb meem - huab cua nyob rau hauv pem hauv ntej thiab tom qab lub diaphragm yog compressed, lub suab yoj "luv" nyob rau hauv cov kab noj hniav, thiab qhov tshwm sim yog tus tsav tsheb ntsiag to.
Xaiv 0.5W rated yog qhov chaw qab zib rau cov kab noj hniav no: nrov txaus yam tsis tau tsav lub diaphragm mus rau hauv cheeb tsam uas tsis yog -linear. Yog tias cov neeg siv khoom qhia "muffled low-frequency" tawm tswv yim, tus tsav tsheb tsis tshua muaj qhov teeb meem - nws yog kab noj hniav uas tsis muaj lub qhov cua lossis lub siab valve. Ntxiv 0.3 ~ 0.5 hli siab qhov cua yuav du 200 ~ 500Hz band. XDEC tau hloov kho 50+ saib cov ntaub thaiv npog rau Φ15 × 8mm B-chav kawm tsav tsheb, nrog rau pem hauv ntej- kab noj hniav qhib tus nqi feem ntau tswj ntawm 8% ~ 15%.
Pitfall 3: IP68 waterproofing ≠ "tus hais lus tuaj yeem ntub dej" - acoustic membrane yog ib yam khoom siv hluav taws xob
Lub smartwatch ntsuas IP68 txhais tau tias tag nrho cov cuab yeej muaj sia nyob 1.5 meters hauv qab dej rau 30 feeb yam tsis muaj dej nkag. Tab sis tus hais lus lub suab yuav tsum ua pa - suab mus los ntawm huab cua kev co, yog li sealing tus hais lus lub qhov kiag li tua cov zis. Yog li ntawd, tus neeg hais lus IP68 yuav tsum tau ua ke nrog cov khoom siv tsis muaj dej tsis muaj dej: lub membrane nws tus kheej tsis muaj dej tsis zoo (IPX7 lossis siab dua), thaum nws cov acoustic tsis kam txwv qhov SPL poob (feem ntau tsawg dua lossis sib npaug rau 2dB @ 1kHz).
Ib qho yuam kev feem ntau yog kev yuav cov "hais lus" thiab "waterproof membrane" cais, tsuas yog nrhiav cov specs tsis sib xws - lub membrane cov cua ntws tsawg dhau, poob SPL ntau dua 5dB; los yog daim nyias nyias lub siab ua haujlwm tsis txaus, deforming tom qab IP68 tsau tshuaj ntsuam. Txoj hauv kev kom raug yog tsim tus neeg hais lus thiab acoustic daim nyias nyias raws li ib qho acoustic system: daim nyias nyias, thaj chaw, thiab txoj hauj lwm yuav tsum phim tus neeg hais lus hauv ntej kab noj hniav. XDEC muab cov dej tsis sib xyaw ua ke- cov tshuaj membrane los yog cov khoom sib xyaw ua ke- tsuas yog muab khoom.
Pitfall 4: 900Hz F0 + 81dB rhiab heev - ntsuas qhov chaw nrov nrov ua ntej
Lub 900Hz resonant zaus (F0) zaum hauv nruab nrab -tsawg band, sib xws rau 200 ~ 800Hz tib neeg lub suab qhov tseem ceeb, yog li lub suab hu kom meej meej. Txawm li cas los xij, 81 ± 3dB rhiab heev hauv 70 ~ 80dB ambient suab nrov ib puag ncig (subway, khw) tsuas yog txaus thaum tuav rau pob ntseg - nws tau nyias thaum lub dab teg tuav 20cm deb.
Yog tias cov khoom siv tseem ceeb yog "kev ceeb toom suab + dab teg- tsa hu," 81dB txaus. Yog tias cov ntaub ntawv siv tseem ceeb yog "tes- hu dawb hauv ib puag ncig tsis muaj suab nrov," qhov siab dua -rhiab heev version (85dB+) raug pom zoo, lossis ntxiv DSP tau txais nyiaj them poob haujlwm. Tsis tas li ntawd, 900Hz diaphragm distortion nyob ze 1kHz feem ntau tsawg dua lossis sib npaug li 1%, tab sis thawb mus rau 0.8W siab tshaj lub zog, kev cuam tshuam yuav tsoo 5% sab sauv txwv - lub smartwatch yuav tsis ncav cuag qhov no hauv kev siv ib txwm, tab sis nws tseem ceeb thaum lub sij hawm EMC kev sim lossis ntev -}rov qab ua si siab - lub sijhawm ua si siab
